  • Frequency modulation device, switching power supply and frequency modulation method thereof
    Patent number: 11728726
    Abstract: The present disclosure relates to a frequency modulation device, a switching power supply and a frequency modulation method thereof. The device includes: a waveform generation unit (10) configured to generate a periodic signal required for performing frequency modulation on a clock signal of a switching power supply to be controlled; a frequency modulation unit (20) configured to perform voltage-current conversion and arithmetic processing based on the periodic signal to obtain a frequency modulation current required for performing the frequency modulation on the clock signal of the switching power supply to be controlled; and an RC oscillation unit (30) configured to perform RC oscillation processing based on the frequency modulation current to obtain a frequency oscillation signal as the clock signal of the switching power supply to be controlled.
